We have a table with around 150+ million records and our database is setup with two nodes on rac. We can’t do no logging as it’s default setup with logging in prod.

We have a requirement to add two columns for this big table and we need to perform update operation for existing records based on another table.

What is the best approach to achieve this with logging.
